STANCHION.

Appfication filed February .24, 1919 Serial no. 278,905. h

10 luiving paired standards, of which one is .movablv connected to the other, and the object? of iny improvement is to furnish a novuhly linked connection for such standards, and manually operable fastening ineansfor separably securing them together in a closed position relative to each other.

\ \This object I have accomplished by the 7 means which are hereinafter described and claiined, and which are illustrated in the accompanying drawiugs.inwhich Figure 1 is an elevation of my improved stanchion and its supporting means, with parts broken away; Fig. its a detail elevation of the stanchion. partially in section, with the inovable standards thereof," swung outwardly; l g. is ,a top plan view of the stanchion shown in said F 2, and Fig. e. is an enlarged detail sectional view of the pivotal connection oi. the n'iovablc standard.

Similar numerals of reference denotecorresponting parts throughout the several views. 1 I V a My iinprored stanchion is composed of a fixed standard 1' and a swinging standard 2 with cross connections 3 and 23 at the top and bottom respectively. Said cross connections have respectively grooved sockets 16 and 21 within which'are fixedly mounted the ends of the standard 1, both of the stand- 40 ards 1 and 2 being made of T-bars, but may ard 2 sloped inwardly, and'the standard 2' is pivotally mounted insaid socket on a pintle 25. On opposite sldes of the Web of said standard are fixed spacing-plates 26 which fill up'the interspa'ces' between opposite sides of said web and opposite walls of said socket to contact therewith. The inclined wall part 24; of said socket affords room for the standard 2 to swing outwardly Specification of Letters Patent.

restrictedly, but the upper angle thereof serves as a stopto liinit swinging movement of the standard in the opposite direction. The upper cross-connection 3 has a" verti- 1 1' 1 caily disposed slot l through which is passed the pintle 5 onnecting the depending ine1n hers of a swivel 6. The nu neralgl denotes a-pair of spaced vertical posts set fixedly in a solid base inade of concrete or other. niaterial. Said, posts are connected their tops by a cross-beam 32 mounted in pairs 01 clsnipingnienibers A hook 8 is fixed dependingly in the middle of the cross-beam 32, and the swivel 6 is connected to said hook by several chain links 7 said means, the stanchion is swingingly supported and freely inovable in any direction, but will always returnautomatically to the normal plane oi is position between and relative to said posts, because of the directive action of said chain links and swivel connection in the slot 4. The lower cross-connection has horizontally disposed slot 27 receiving a ring An eye-bolt 29 whose shank is bent, angularly and fixed within the base 30, is connected to the ring 28 by several chain links, which permit restrictive movements or the stanchion in any direction. p

The upper end of the swinging stanchion 2 is inovably linked to the upper cross connection S by the following means: Said upper' cross connection has a longitudinal tubular hollow 18 open through a socket l t, the latter adapted to seat the upper end of the,

standard 2. A. beef; is fixed upon the upper end of the standard 2 provided with an out wardly directed integral fork 19 adapted to span the acent post 31 to limit movement of the stanchion when said standard 2 is swung outwardly. Said body also has an upwardly directed detent 17. The numeral 20 denotes an elongated loop, the ends of 1 which are swinginglyconnected to said body on pivots 85.- The loop 20 1s receivable and movable slidably within the hollow 18 of said cross connection 3, and is prevented from escaping'froin said hollowby means of Va fixed stud or pin 34tfiXed across said hollow near its outer end within said loop. 7 The cross connection ,3 has spaced parallel longitudinal ribs 36 on its top between which is mounted a lever 10 medially pivoted on a pintle 9, and having one end enlarged at 13 and provided with a downwardly directed engaging-means 12 thereon 'wlth the detent 17.

When the niovable standard 2 is in the position shown in said Fig. 2, itmay beswung inwardly, thus sliding the loop 20 into the hollow -18 of the cross-section Snntil the up,-

per end of the standard is'received between the forks of the socket 1 L. Sald standard isso located relatively to the socket 14 that when swung inwardly, it will not completely lit-said socket without slightly bending, and since the T-bar part of said' 'standardis somewhat elastic, it will yield sufficiently for the purpose, when, as shown in Fig. a, it is engaged with the angle of the sloping inner wall 2% of the lower socket-22, the pintle serving as iii-11118111111. It is only in this position that thedetent 17 will be immediately below the socket 12 of the trip-lever 10, and since this end of said lever is heavier than its other end, itwill drop and receive said detent within its socket, which securely fas tens the standard 2 to the trip-lever because the elasticreaction of the standard causes "thesloping face of the detent to interlock V withthe abutting slopingvinner wall of the socket 12. The standard 2 maybe spread apart to its first position by simply depress ing the finger-piece 11 of the trip-lever, which draws back the standard elastically enough to cause the detent '17 to escape from the socket 12 as the head 13 of the lever is swung upwardly. This drawing inwardly of the standard 2 has again placed it under tens on, and. on the release of the detent 17,

the reaction of said tension is sufiicient to thrust outwardly the standard slightly beyond the center of gravity so that, under the influence of gravity, it will swing outwardly,

' withdrawing the loop 20 from the socket 18,

and engaging the forks 19 with the adjacent .post31. s

the engaging-means on saidother stander-u.

It shouldbe noted that the looped bar 20 is 01 relatively great strength transversely, and guides theupper end of the standard directly into thesocket 1 1 without iaihwhile v the support afforded by this bar to theupper end 01 the standard takes awaystrain from the hinged connectionat its lower end, preventing breakage in the hinge, or bond 7 ing of the standard it pushed violently by a shoulder of the'cow.

When the standard 2 is swungto its closed position, the clash of its upper part with the socket 14 reacts on the pivoted lever or oat-ch 13 to shakethe latter into engagement with the projection 17 and prevent sticking or the lever 'on its pintle.

The means shown are easily operated manually, act automatically when the initial impulse has been given, whlle the locking action is such that the parts cannot be separated by ordinarys ocks and jars,,andin fact, only by a positive depressionof the I finger-piece 11, of said trip lever.

Having thus described my invention, what .I claim asnew, and desire to'sccnre by-Lot ters Patent, is: V

In combination, a pair 0 it;pivotally connected stanchion standards, a cross-connecting body fixed tothe top of one standard and provided with a raised part having a vverticallyelongated orifice, engaglng neans on the upper end of the other standard, a trip-lever having enga'ging-mcans to mate with the other engaging-means and pivoted 'on said cross-connection,said 1 Ver extending above said elongated orifice, and supportingmeans including a pi-ntle passed through said elongated orifice to'support tho or connection movably while engaging the sin per-posed part of said leverto keip the cit gaging-means thereonin engagement with I Signed at Monticene a this 7th air, or Feb. ,1919. -1
